Redmine Infrastructure - Bug #8866 (New): Java client tools should set a custom user agent stringhttps://redmine.dataone.org/issues/88662020-07-15T18:03:40ZBryce Mecummecum@nceas.ucsb.edu
<p>Related to <a href="https://redmine.dataone.org/issues/7047">https://redmine.dataone.org/issues/7047</a></p>
<p>It looks like nowhere in <code>d1_libclient_java</code> do we set a user agent string. Aside from being best practice, it limits our ability to customize our infrastructure around it. For example, OPC is running into HTTP 413s due to overrunning their TLS renegotiation buffer and we can't effectively whitelist their requests, which come from our Java client tools, to allow them to upload large files.</p>
CN REST - Bug #8860 (New): /token endpoint doesn't set a content-type and character encodinghttps://redmine.dataone.org/issues/88602020-02-29T01:00:11ZBryce Mecummecum@nceas.ucsb.edu
<p>On Firefox only, requests to the /portal/token endpoint (i.e., the one MetacatUI and other clients use to fetch their auth tokens, like <a href="https://cn.dataone.org/portal/token">https://cn.dataone.org/portal/token</a>) result in errors in the browser console.</p>
<p>When you access the URL via an XHR request, you see:</p>
<blockquote>
<p>XML Parsing Error: syntax error<br>
Location: <a href="https://cn-stage.test.dataone.org/portal/token">https://cn-stage.test.dataone.org/portal/token</a><br>
Line Number 1, Column 1:</p>
</blockquote>
<p>When you access the URL directly in Firefox:</p>
<blockquote>
<p>The character encoding of the plain text document was not declared. The document will render with garbled text in some browser configurations if the document contains characters from outside the US-ASCII range. The character encoding of the file needs to be declared in the transfer protocol or file needs to use a byte order mark as an encoding signature.</p>
</blockquote>
<p>I had a hunch that this error would go away if the response simply had the <code>Content-Type</code> header set to <code>text/plain; charset=utf-8</code> so I spun up <code>mitmproxy</code>, made that edit to the intercepted response, and saw that the error does go away.</p>
<p>I think we should modify the portal code to set the <code>Content-Type</code> header like above so the error goes away.</p>

Infrastructure - Bug #8821 (New): Object doi:10.18739/A2610VR7Z fails to index on CNhttps://redmine.dataone.org/issues/88212019-06-18T22:43:38ZBryce Mecummecum@nceas.ucsb.edu
<p>I noticed <a href="https://search.dataone.org/cn/v2/meta/doi:10.18739/A2610VR7Z">https://search.dataone.org/cn/v2/meta/doi:10.18739/A2610VR7Z</a> isn't present in the search index and asked about it on DataONEOrg #ci Slack channel. Chris noted that no no task was in the index queue for the PID. He tried to force a reindex which failed. He couldn't find a log entry indicating why it failed so someone needs to look into what's going on. It occurs to me that whatever bug is affecting this Object may have affected more Objects so a second part of fixing this bug should probably be doing some housekeeping or an audit of some kind to make sure the search index isn't missing more content.</p>

Infrastructure - Bug #8612 (Closed): Improperly formatted Alternate Data Access URLshttps://redmine.dataone.org/issues/86122018-06-12T22:37:39ZBryce Mecummecum@nceas.ucsb.edu
<p>If I go to</p>
<p><a href="https://search.dataone.org/#view/urn:uuid:8d639e70-55eb-40aa-b1a4-29712fd31b63">https://search.dataone.org/#view/urn:uuid:8d639e70-55eb-40aa-b1a4-29712fd31b63</a></p>
<p>and look at he underlying URL in the Address field, I see:</p>

<p>Looks like the underlying XSLT isn't going deep enough down the path hierarchy</p>
Infrastructure - Task #8499 (New): Improve rendering of http://www.isotc211.org/2005/gmd-pangaea ...https://redmine.dataone.org/issues/84992018-03-14T00:49:31ZBryce Mecummecum@nceas.ucsb.edu
<p>I offered to file this a while back but it just sat in my inbox.</p>
<p>Initial support for rendering went in with <a href="https://redmine.dataone.org/issues/8219">https://redmine.dataone.org/issues/8219</a> but we noted in Slack in #ci that the rendering could be a lot better. As an example of how much better, Pangaea's own landing pages are quite nice: <a href="https://doi.pangaea.de/10.1594/PANGAEA.511392">https://doi.pangaea.de/10.1594/PANGAEA.511392</a></p>
<p>Upon checking the first Pangaea dataset in the index, <a href="https://search.dataone.org/#view/af113afed60c98df50052feaf6cb7894">https://search.dataone.org/#view/af113afed60c98df50052feaf6cb7894</a>, I see that the view service isn't actually working at all for this document. So I guess this could be two tasks:</p>
<ol>
<li>Enable the Metacat View Service for Pangaea docs</li>
<li>Improve the XSLT</li>
</ol>
<p>2 just involve extending the existing isotc211 XSLT if we think that other isotc211 creators want those fixes but if we want to make a nice view that's Pangaea-specific, we may want to consider a separate stylesheet suite.</p>
Infrastructure - Decision #8189 (New): Proposal to change the roles mapped to the origin Solr fie...https://redmine.dataone.org/issues/81892017-10-02T18:04:37ZBryce Mecummecum@nceas.ucsb.edu
<p>While discussing changing the behavior of the origin field in the ISO indexing component (<a href="https://redmine.dataone.org/issues/8165">https://redmine.dataone.org/issues/8165</a>) to make it more selective about where in the document originators are pulled, Matt Jones (over email) suggested we revisit the set of roles as well. Let's do that in this Issue.</p>
<p>The current set of roles mapped to the origin field are:</p>
<ul>
<li><em>originator</em>: party who created the resource</li>
<li><em>author</em>: party who authored the resource</li>
<li><em>owner</em>: party that owns the resource</li>
<li><em>principalInvestigator</em>: key party responsible for gathering information and conducting research</li>
</ul>
<p>This current set of roles may be surprising to some/many users so a possible outcome of this Issue is to greatly improve the content in our search index. This would have impacts on the CN and MNs running Metacat.</p>
<p>Key points:</p>
<ul>
<li>Matt's proposal is to exclude principalInvestigator from this list</li>
<li>The Research Workspace Member Node appears to be using the principalInvestigator role for one or more persons they want in their citation so if we follow Matt's proposal we may need to discuss this with them</li>
<li>I would lobby for only including originator and author but my reading of the definitions is a naïve one</li>
</ul>
<p>I'd like us to have a discussion on this, make the relevant change to the codebase, and then bring the discussion back to the MN operators.</p>

Infrastructure - Task #8165 (Closed): Re-factor origin field in isotc211 indexing componenthttps://redmine.dataone.org/issues/81652017-08-29T22:40:30ZBryce Mecummecum@nceas.ucsb.edu
<p>The xpath selectors we use in the origin field in the isotc211 indexing component (bean?) were found to be incorrect for a particular use case and a larger group of us agreed that the usage was incorrect. We should re-visit which xpaths are being used, re-deploy, and re-index the affected content.</p>
<p>I'm pasting in an email chain that initiated the creation of this Issue so we have the full background:</p>
<p>From Chris Turner at Axiom</p>
<blockquote>
<p>Hi Laura and Matt,</p>
<p>Since the launch of the Research Workspace member node, we've no noticed that the dataset citation given at the top of the page doesn't match how we or the PIs would like the official citations to be formatted. There are two issues: selection of contact names for the citation, and appearance of the DOI. </p>
<p>It looks like contact names are being pulled from several parts of the metadata record, the section describing the resource itself (gmd:MD_DataIdentification/gmd:citation/...) and from the section describing associated or aggregated resources (gmd:MD_DataIdentification/gmd:aggregationInfo/...). Here are two examples:</p>
<p>Mary Anne Bishop, Ben Gray, and Scott Pegau. 2017. Fish Predation on Juvenile Herring in Prince William Sound, Alaska, 2009-2012, EVOS Prince William Sound Herring Program. Research Workspace. 10.24431/rw1k1z.</p>
<p>Mary Anne Bishop, Anne Schaefer, Kathy Kuletz, Molly McCammon, Katrina Hoffman, et al. 2017. Fall and Winter Seabird Abundance Data, Prince William Sound, 2007-2017, Gulf Watch Alaska Pelagic Component. Research Workspace. 10.24431/rw1k1w.</p>
<p>In the first exmaple, Scott Pegau is listed in the dataset citation, though in the metadata he is not connected to the dataset but to as the PI for the Herring Program, a larger work referenced in the 'aggregationInfo' section. The second example is the same - McCammon, Hoffman, et al. are pulled from the 'aggregationInfo' element. </p>
<p>Please let me know if I understand correctly how the contacts are being selected for the citation. If I do have it right, is there anything that we can do about it, on our end or in the member node? </p>
<p>The DOI display issue is simpler. DataCite and CrossRef best practices are that DOIs should be displayed as complete URLs, with '<a href="https://doi.org/">https://doi.org/</a>' appearing before the DOI code assigned to a resource. That's how they're formatted in the metadata records, but the URL-esque formatting is stripped out for the citation and for display in the member node.</p>
<p>Can we display the DOI, both in the citation and in the metadata page as a full link?</p>
<p>Please advise on the best way to remedy these. I apologize if this is not the correct venue for this conversation. Please let me know if it makes more sense to continue talking about this on Slack.</p>
<p>Thanks in advance for your help.</p>
<ul>
<li>Chris</li>
</ul>

<p>From Matt Jones:</p>
<blockquote>
<p>Bryce worked on a new stylesheet for ISO metadata, and so that is scheduled to be released soon. So, any changes would be good to propose even sooner to get them folded in. </p>
<p>If I am interpreting Chris correctly, he's saying that we are indiscriminately pulling Responsible_Party entries regardless of their context in the document, and that it would be best practice to only cite the ResponsibleParty instances that are part of the citatiion in gmd:MD_DataIdentification/gmd:citation/. This makes total sense to me, and is what we do with other metadata standards. So, we need to look into what is causing the behavior, and figure out if it is a stylesheet change, an indexing change, or both. </p>
<p>Matt</p>
</blockquote>
<p>From Chris Turner:</p>
<blockquote>
<p>Hi all, <br>
Matt's understanding is correct. As it is now. ResponsibleParty elements are being pulled in independent of where they appear in the record. Doing as he says and pulling only from gmd:MD_DataIdentification/gmd:citation would go be a good simple fix. We'd also like the pull the contact name from gmd:MD_DataIdentification/gmd:pointOfContact, too.<br>
I'm available the September 5th-8th to chat if we need to talk that week. </p>
<p>From Laura Moyers:</p>
<p>Thanks, Chris! </p>
<p>Matt, do you think what Chris describes would be a stylesheet change that Bryce could incorporate into his current changes? Would we need to talk with other ISO metadata users about this?</p>
<p>Thanks<br>
Laura</p>
</blockquote>
<p>From Matt Jones:</p>
<blockquote>
<p>I suspect it should be straightforward, and Bryce may have already handled it. We were just talking yesterday about getting his stylesheet changes into a Metacat release and deployed on the CN -- its been in a holding pattern for some reason. So, Jing and Bryce are going to work on getting those display improvements pushed out, as they were requested by a number of members. I don't think Chris' proposal would be at all controversial -- our current display is clearly misleading and would be improved, so I think its a clear win. So. I'll cc Bryce and hopefully he can comment on whether and what work would be needed to support proper citation displays for ISO records.</p>
<p>Matt</p>
</blockquote>
<p>From Rob Nahf:</p>
<blockquote>
<p>Will these discussed changes also be reflected in the DataONE solr index? If so, we would likely need to reindex all content of that format after making changes to the parser.<br><br>
(It sounds like there's broad community support for the change, so reindexing probably wouldn't negatively impact anyone...)</p>
</blockquote>
<p>From Bryce Mecum:</p>
<blockquote>
<p>Hey all: Yes, as Matt guesses this is pretty straight forward to fix. The dataset citations in our search and landing pages are powered by our Solr index and we would just need to change the relevant indexing routine and reindex the content. After a quick look at how things are working now, I agree that some change is needed. The information contained in this thread is super helpful so thanks, Chris, for the high level of detail in your original email.</p>
<p>All of that work is on our end and I can coordinate with the DataONE CI team on the changes and we'll let everyone here know when the changes have been made.</p>

Infrastructure - Bug #8052 (New): Geohashed value is incorrecthttps://redmine.dataone.org/issues/80522017-03-27T20:43:47ZBryce Mecummecum@nceas.ucsb.edu
<p>Adam Shepherd at BCO-DMO uploaded a test DCX doc here:</p>
<p><a href="https://search-sandbox.test.dataone.org/#view/http://lod.bco-dmo.org/id/dataset-file/682007">https://search-sandbox.test.dataone.org/#view/http://lod.bco-dmo.org/id/dataset-file/682007</a></p>
<p>which has bounding coordinates of:</p>
<p>North<br>
50.4907 degrees<br>
South<br>
20.4907 degrees<br>
East<br>
-120 degrees<br>
West<br>
120.826 degrees</p>
<p>and when we looked at the geohash values stored in the index for the record they appear to be incorrect. The bounding coordinates this DCX record is using are a bit weird but I'm not sure they're invalid. Google's JavaScript maps API calculates the centroid as 35.490700000000004,-179.58700000000002 which, according to this tool, <a href="http://www.movable-type.co.uk/scripts/geohash.html">http://www.movable-type.co.uk/scripts/geohash.html</a>, should have a geohash of 8n23ckusk but has a geohash of sn23ckusr instead, which is nearly 180 degrees longitude away from the expected location.</p>
Infrastructure - Bug #8043 (New): The origin field for EML documents isn't properly extracted whe...https://redmine.dataone.org/issues/80432017-03-10T21:36:25ZBryce Mecummecum@nceas.ucsb.edu
<p>We just ran into this with the following EML record: <a href="https://knb.ecoinformatics.org/#view/doi:10.5063/F15B00CC">https://knb.ecoinformatics.org/#view/doi:10.5063/F15B00CC</a></p>
<p>The EML has six creators (Kiesecker, Fargione, Baruch-Mordo, Trainor, Ryan, Patterson) but the origin field in the Solr index has two (Ryan, Patterson). After some digging, we realized this was likely because the indexing component responsible for EML doesn't respect EML references. The XML for the relevant section is:</p>

Infrastructure - Bug #7858 (New): Obsoleting a resource map clears the resourceMap field for the ...https://redmine.dataone.org/issues/78582016-08-03T21:34:03ZBryce Mecummecum@nceas.ucsb.edu
<p>This is long-standing behavior that I consider a bug. That said, there are likely plenty of design conversations that predate me I'm unaware of.</p>
<p>When I update a Data Package by updating the metadata object and its resource map with new ones, the resourceMap field in the Solr index for the obsoleted metadata object is cleared. I expected it not to be cleared.</p>
<p>Why is this the way it works? The way I see it, clearing out the resourceMap field in the Solr index for the obsoleted metadata object reduces benefit of us versioning objects. When a package is cited by its metadata object's PID and the package is updated after the citation was published, a visitor to the dataset landing page will no longer see the package because the resource map isn't in the index. Of course they will be shown a link to the latest version of the package which does have a resource map but that's not what they cited.</p>
Infrastructure - Story #7668 (New): Determine how indexing of data packages should workhttps://redmine.dataone.org/issues/76682016-03-02T00:16:25ZBryce Mecummecum@nceas.ucsb.edu
<p>I've discovered (with Lauren's help) a strange requirement for how the resource maps for nested data packages have to be written. In order to get nested data packages correctly indexed in Solr so that the 'resourceMap' field of the resource map being nested is set to the parent resource map's PID, you have to create the appropriate set of @cito:documents@ statements in addition to the expected @ore:aggregates@ statements.</p>
<p>I expected the following to be sufficient (pardon the highly abstracted RDF, examples are linked below):</p>
<p>parent_resource_map#aggregation ore:aggregates child_resource_map<br>
parent_resource_map#aggregation ore:aggregates metadata_object</p>
<p>but I also had to add a @cito:documents@ statement between the <em>parent resource map's metadata object</em> and the resource maps being nested</p>
<p>parent_resource_map#aggregation ore:aggregates child_resource_map<br>
parent_resource_map#aggregation ore:aggregates metadata_object</p>
<p>parent_metadata_object cito:documents child_resource_map</p>
<p>The documentation does not suggest this and I found it confusing. A real life example of what I expected to work is here: <a href="https://gist.github.com/amoeba/c7a6ba269c5a1f78db1d">https://gist.github.com/amoeba/c7a6ba269c5a1f78db1d</a><br>
What I actually had to insert is here: <a href="https://dev.nceas.ucsb.edu/knb/d1/mn/v2/object/resourceMap_urn:uuid:ab17b047-a341-4d06-b433-92eed90dacec">https://dev.nceas.ucsb.edu/knb/d1/mn/v2/object/resourceMap_urn:uuid:ab17b047-a341-4d06-b433-92eed90dacec</a></p>
<p>Is the need for the @cito:documents@ statement(s) really required and is this the intended behavior? I've made this issue in the hopes we can talk about it.</p>
<p>I suggest updating the API docs with whatever we decide, and hopefully that update will include example RDF for a nested data package.</p>
DataONE API - Bug #7578 (New): Fix 404 link to d1_instance_generator folder in documentationhttps://redmine.dataone.org/issues/75782016-01-08T22:01:20ZBryce Mecummecum@nceas.ucsb.edu
<p>In the MN API documentation for MNStorage.create (<a href="https://jenkins-ucsb-1.dataone.org/job/API%20Documentation%20-%20trunk/ws/api-documentation/build/html//apis/MN_APIs.html#MNStorage.create">https://jenkins-ucsb-1.dataone.org/job/API%20Documentation%20-%20trunk/ws/api-documentation/build/html//apis/MN_APIs.html#MNStorage.create</a>), I found a the following paragraph contains a broken link to d1_instance_generator:</p>
<blockquote>
<p>"The system metadata included with the create call must contain values for the elements required to be set by clients (see System Metadata). The system metadata document can be crafted by hand or preferably with a tool such as generate_sysmeta.py which is available in the d1_instance_generator Python package. See documentation included with that package for more information on its operation."</p>
</blockquote>
<p>The link to d1_instance_generator was to the SVN folder <a href="https://repository.dataone.org/software/cicore/trunk/d1_instance_generator">https://repository.dataone.org/software/cicore/trunk/d1_instance_generator</a> which is currently a 404. I think the folder moved to /d1_test_utilities_python/src/d1_test/instance_generator.</p>
Infrastructure - Task #7466 (In Progress): Some objects not accessible on the CN via REST APIhttps://redmine.dataone.org/issues/74662015-11-04T18:41:38ZBryce Mecummecum@nceas.ucsb.edu
<p>While doing other work, I noticed that a good number (not sure how many) of objects listed on the CN's Solr index are not accessible via the REST API get() and resolve() methods. Instead of returning the object, they return a NotFound error. </p>
<p>To reproduce,</p>
<ol>
<li>Visit <a href="https://cn.dataone.org/cn/v1/query/solr/?fl=identifier,title,authoritativeMN,datasource&q=formatType:METADATA+AND+-obsoletedBy:*&rows=100&start=0">https://cn.dataone.org/cn/v1/query/solr/?fl=identifier,title,authoritativeMN,datasource&q=formatType:METADATA+AND+-obsoletedBy:*&rows=100&start=0</a></li>
<li>Pick a PID from the query result, e.g.</li>
</ol>
<ul>
<li>knb-lter-cap.148.9</li>
<li>CLOEBDMETADATA.10242013.1</li>
</ul>
<ol>
<li>Attempt to resolve() or get() the object via the REST API like: <a href="https://cn.dataone.org/cn/v1/object/CLOEBDMETADATA.10242013.1">https://cn.dataone.org/cn/v1/object/CLOEBDMETADATA.10242013.1</a></li>
<li>Receive a NotFound error instead of the object.</li>
</ol>
<p>Notes:</p>
<p>In IRC, Skye noticed that the objects can be retrieved via their respective MN so it appears this issue may be a Metacat replication issue.</p>
